Summary

ELECTRICAL ENGINEER with a broad range of experience in hardware and firmware design and product development for the telecommunications and defense industries (previously held Department of Defense Security Clearance). Specific areas of expertise include power circuit design and embedded systems programming. I am seeking an ELECTRICAL ENGINEERING, EMBEDDED SYSTEMS DEVELOPMENT, FIRMWARE DEVELOPMENT or SOFTWARE DEVELOPMENT position in the Jacksonville, Florida region providing opportunity for technical growth and skill enhancement. I would also consider a telecommuting (virtual) position.

Jul 2004 - Dec 2009
  • Responsible for architecture, circuit design, development and testing of a two kilowatt system level power solution for a low cost CDMA 3G Base Station that was developed for customers in China and India.
  • Resolved field issues with existing widely deployed base station power supplies. Successfully identified the root causes of the problems and implemented corrective actions by working with 3rd party suppliers.
  • Leader of two international Supplier Quality Improvement Teams (Delta Electronics, Thailand & Tyco, Mexico).
  • Authored Power & Battery Engineering Rules Documents for various base stations. These documents are used to support Configurator Tool Software Releases and guide customers in how to set up and grow their wireless networks.
  • Supported the establishment and growth of a reference library of reusable power sub-circuits or platforms that were used to support company-wide cost reduction and new product introduction efforts.
  • Actively supported the Optical Networking Group’s Cost Reduction Program: Submitted power circuit cost reduction proposals and monitored progress, maintained Cost Savings Tracking Workbooks, participated in brainstorming sessions and authored follow-up White Papers to describe design-related cost avoidance ideas.
  • Provided circuit pack power subsystem design support. This included detailed load analysis, creation of Excel Spreadsheet Power Workbooks, assistance in the selection of parts, circuit design, participation in design reviews, etc.
  • Developed an ATCA High Voltage Energy Storage Circuit and evaluated its performance over a wide temperature range. Successfully deployed this circuit on four different circuit packs.
  • Provided input into the Supply Chain Network’s Board Mounted Power and Power Management Circuit Strategies.
  • Supported Supply Chain Network’s efforts to respond to Ambit/Foxconn/Hon Hai’s decision to exit the power business.

Firmware Architect, Designer and Developer
Telecommunications
Jul 1993 - Jun 2004

Firmware Architect, Designer and Developer – Multiple Network Announcement & Interactive Voice Response Products:

  • Developed the Board Support Package (BSP) to interface the VxWorks 5.5 Operating System to an IBM NPe405L Network Processor. The BSP was written in Assembly Language and C Language.
  • Designed and developed a device driver for Intel StrataFlash Memory used for storage of Operating System Images, Bootloader Images, FPGA Images, System Logs and Built-In Voice Prompts.
  • Designed a custom multilayer dynamic state machine providing call processing of 24 simultaneous calls that are receiving different announcement services, providing a remote voice prompt based administration interface and providing a remote PC Workstation-based data administration interface.
  • Wrote extensive application layer C/C++ code using a Tasking C/C++ Compiler/Assembler/Linker/Utilities/IDE Package for the Philip’s XA-G3 Microprocessor.
  • Used a Nohau EMUL51XA-PC In-Circuit Emulator with trace board and a Tasking ROM Monitor Debugger with simulated I/O capability to debug the code at both the high level language and assembly language levels.
  • Gained familiarity with 5ESS signaling protocols.

Digital and Analog Circuit Designer and Developer – PBX Announcement System:

  • Designed and developed electronic circuitry for a product that was based upon two Intel 80C52 8-Bit Microcontrollers.
  • Wrote firmware using an Archimedes C Language Compiler.

Computer Workstation Hardware & Software Integration – Telecommunications Network Announcement Administration:

  • Identified and tested new computer hardware to support the continued use of legacy software and device drivers that provide the capability to program 5ESS Switch Voice Announcement Sets on PCMCIA Flash Cards.
  • Developed detailed production staging procedures to be used by the manufacturer. Tested updated software and revised User’s Guide, Online Help and other product technical documentation. Created field upgrade kits.
